    Quite a bit actually. There are quite a few products using the Hope RF modules. Jeelabs, strobotics, openenergymonitor, lowpowerlab. etc.

    Some details on range here: http://talk.jeelabs.net/topic/180

    Google ‘RFM12B range’ (I think the unit above is similar, can’t be sure as the datasheet links to the old module) for more info.

    I made mine work in a breadboard by bending the tops of a breakout header to fit the spacing. Pins 1 and 14 (or was it 7 and 8…) aren’t required for use with an ATMega - one is a 2nd GND that can be wired to the other ground without connecting the header, I don’t remember what the other pin is… Anyway, that works somewhat. Agree about the breakout though - see my question below.

    Will there be a real breakout this time? The one ‘below’ is for the RFM22 which has more pins. Also, I assume the arduino thield for the 22 can’t be used for the 12, or is the SPI and power pinout he same?

    Awesome - seems fixed to me using Feedly.

    The latest ‘new product’ in the feed is “Timing Belt - XL (per foot) (ROB-12156)” - the feed hasn’t been updated since Feb 21st.

    Did someone accidently the new product RSS feed? https://www.sparkfun.com/feeds/products

  • Product WIG-12005 | about 9 months ago

    Does is come with a 100ft water resistant smartphone?

    You mean this link? It reads more like a sales pitch than an objective piece about motor rebuilding.
    Saturation is a property of electromagnets, not permanent magnets. Not sure what they’re trying to get to there.
    As for the disassembly story - permanent magnets don’t demagnetize that easily.
    I do think however that since tolerances are quite narrow, disassembly can easily lead to misalignment, which in turn will lead to loss of torque.
    Overcurrent would be able to demagnetize though: see WikiPedia.

    Yep: page source states charset=iso-8859-1 but the ‘degree’ symbols only show up with UTF-8 encoding…

  • Product DEV-10523 | about 3 years ago

    Is that a sticker on the ATMega328?

No public wish lists :(
